Walter Mazzarri wants to see the real Napoli against Lazio tomorrow, after Sunday's disappointing draw with Catania.

The Azzurri played against 10-men for almost 90 minutes in Sicily after Pablo Alvarez was red carded, but failed to break down an organized Elefantidefence.

“Against Lazio I want to see my Napoli,” Mazzarri told Gazzettadello Sport. “Playing as a team we can win.”

The match pits second against third in Serie A, and the former Livorno tactician is well aware his team must improve to emerge victorious.

“Tomorrow there must be competitiveness, nastiness and attention to detail. The modern game is based on a concept, you have to be fierce and high-paced, playing the ball incisively, but I didn’t see this against Catania.

“If we show these qualities against Lazio we would give a bad impression. And this is what I told the players after the trip to Sicily.”

Mazzarri confirmed that some changes will be made, but there will be no starting berth for rising star Lorenzo Insigne.

“EdinsonCavani and GoranPandev deserve confirmation."

Napoli have won only one of the last seven home matches against Lazio in Serie A.
